Find the coefficients of the expansion of (3a−b)3. That is, represent (3a−b)3 as
α0a3+α1a2b1+α2a1b2+α3b3
Try to compute these coefficients using the binomial theorem (instead of multiplying (3a−b) by itself two times).
Enter the values α0,α1,α2,α3. Separate the values by commas, avoid spaces, do not include plus signs.
For example, for the question (3a−b)2 the answer would be: 9,-6,1
Exactly!
